Hi, my name is

Deepak Kumar Sahu.

I |

Senior Engineering Manager leading DevOps, Platform Engineering & Observability at Storable. Founding DevOps hire at India GCC — built the entire function from scratch, now managing 60+ Kubernetes clusters and 1,200+ workloads across 20+ products on AWS.

01. About Me

I was the founding DevOps hire at Storable India's Global Capability Center (GCC), where I built the DevOps, SRE, Platform Engineering, and Observability practices from the ground up. Today, I lead teams that manage infrastructure serving 20+ products across 60+ Kubernetes clusters on AWS.

With 13+ years in the industry, I've progressed from hands-on infrastructure engineering at Mindtree working alongside Microsoft FTEs on Azure production clusters, through building CI/CD pipelines at EPAM, to designing IPL live-streaming infrastructure at Jio, and now leading platform engineering at scale at Storable.

My philosophy: Infrastructure should be invisible. Developers should ship code, not fight tooling.

Here are a few technologies I've been working with recently:

  • Kubernetes (EKS)
  • ArgoCD & GitOps
  • Terraform
  • Grafana Cloud (Mimir, Loki, Tempo)
  • Istio Service Mesh
  • AWS (60+ clusters)

02. Where I've Worked

Senior Engineering Manager @ Storable India

Aug 2023 — Present

  • Led DevOps operations across 20+ products and 60+ EKS clusters on AWS spanning payments, property management, and marketplace verticals.
  • Architected GitOps control plane using ArgoCD app-of-apps with 68 ApplicationSets — targeting 12 product realms and 6 environment types with label-based cluster selection and layered Helm overrides.
  • Defined architecture and oversaw development of a custom Internal Developer Platform (IDP) — Rails 8-backed, single pane of glass across 130+ projects and 1,200+ workloads with real-time AWS/K8s inventory and RBAC release workflows.
  • Built versioned Terraform modules via GitLab registry — CloudWatch + Grafana alerting, secrets management, multi-account support — enabling self-service infra provisioning.
  • Led full migration from Datadog to Grafana Cloud — metrics (Mimir), logging (Loki), and distributed tracing (Tempo) across 60+ clusters and 20+ products.
  • Led cloud migrations (Azure to AWS and GCP to AWS) with minimal downtime; modernised legacy infra dating to 1997.
  • Drove org-wide AI transformation — GitHub Copilot, Claude Code, Glean, N8N, Ollama; built LLM-powered CI/CD code review bot.
  • Conducted deep database performance audits — PostgreSQL internals, query plans, indexing gaps, autovacuum tuning.
  • Managed Istio service mesh across 60+ clusters — mTLS, traffic management, JWT authentication, canary deployments.
  • Established a FinOps practice — built automated right-sizing recommendations, drove tooling migrations achieving 30%+ MoM cost reduction.
  • Built incident management framework with structured postmortems, SLA tracking, and automated escalation.
  • Served as AI Champion for India GCC — conducted seminars and workshops, defined usage policies, led security reviews.
